“A no spatial continuum in which events occur in apparently irreversible succession from the past through the present to the future.” There are things in life, which, in case we loose or damage, we can always gain, buy or obtain them back. Time is not one of them. Once it is gone, there is no way to get it back! Anyway, if you realize that a certain period of your life was less productive or was lost in a way or another, there is no point in crying over spilt milk – there is definitely nothing .
